parallel-compress

Usage

const compress = require('parallel-compress');
webpackConfig.plugins.push(new compress());

Notice

不需要 uglify 插件: webpack.optimize.UglifyJsPlugin

webpackConfig.plugins.some(function(plugin, i) {
  if (plugin instanceof webpack.optimize.UglifyJsPlugin) {
    webpackConfig.plugins.splice(i, 1);
    return true;
  }
});
